The first objective of the workshop is to inform participants about the safety impacts of design alternatives and the availability of tools for evaluating safety impacts. Many of the decisions that designers make on design elements like lane width, median barrier type, or presence of left-turn bays influence the safety performance of the roadway facility being designed. The Workbook was developed to assist with the evaluation of safety impacts for a variety of roadway facility types, including freeways, rural highways, urban and suburban arterials, interchange ramps, frontage roads, and rural and urban signalized or unsignalized intersections. The complex calculations required to implement the Workbook guidance are facilitated by using the TRSD program. The second objective of the workshop is to demonstrate how to use the Workbook and the TRSD program. This demonstration is accomplished with the use of hands-on exercises. At the beginning of each exercise, the participants are given input data describing a roadway facility, including geometry, traffic volumes, area type, traffic control, and other relevant information. The participants are then shown how to enter these data into the TRSD program, obtain information about the safety performance of the facility, and use these results to refine design decisions. After attending the workshop, participants should be able to apply these evaluation tools to typical designs to evaluate the safety associated with the design. This Instructor Guide provides a course instructor with the information needed for course preparation and presentation. Specifically, guidance is provided regarding course handouts and visual aids, equipment requirements, and emphasis of the key messages of the various workshop slides. The front portion of this Guide, titled “Instructor’s Notes,” should be read by the instructor during preparation for the workshop. This material explains the objectives and intended audience of the workshop, describes the necessary materials for the instructor and the participants, and provides a checklist of tasks to be completed before, during, and after the workshop. The second portion of this Guide, titled “Workshop Lesson Slides,” should be reviewed by the instructor before the workshop and kept within view while presenting the workshop. This portion provides detailed information on specific slides in the presentation, including key messages to emphasize during the presentation and background information that can help answer questions from participants. The third section provides additional helpful information in the forms of solutions to the interactive exercises, an acronym and abbreviation list, a glossary, and a list of references and workshop.
